By the way, I think it will be better replace "try to open" with the bitmap name so we can also know about what kind of bitmap we are opening by filename.

Before:

      19:38:43.008724 pack-bitmap.c:536            | d0 | main                     | region_enter | r0  |  0.001160 |           | pack-bitmap  | label:open_bitmap
      19:38:43.008738 pack-bitmap.c:390            | d0 | main                     | data         | r0  |  0.001173 |  0.000013 | bitmap       | ..try to open bitmap:/home/tenglong.tl/test/dyrone/.git/objects/pack/pack-2d1b3f749fb859b874710e33263d0847ef009e03.bitmap
      19:38:43.008754 pack-bitmap.c:543            | d0 | main                     | region_leave | r0  |  0.001191 |  0.000031 | pack-bitmap  | label:open_bitmap

After:
      
      19:38:43.008724 pack-bitmap.c:536            | d0 | main                     | region_enter | r0  |  0.001160 |           | pack-bitmap  | label:open_bitmap
      19:38:43.008738 pack-bitmap.c:390            | d0 | main                     | data         | r0  |  0.001173 |  0.000013 | bitmap       | ../home/tenglong.tl/test/dyrone/.git/objects/pack/pack-2d1b3f749fb859b874710e33263d0847ef009e03.bitmap
      19:38:43.008754 pack-bitmap.c:543            | d0 | main                     | region_leave | r0  |  0.001191 |  0.000031 | pack-bitmap  | label:open_bitmap

Thanks.
